Why we read it this way (7)
The role is explicitly framed as an 'Emerging Professional (Level 2)' position requiring 1+ years of experience and a BS degree, placing it firmly at the Junior band despite some leadership language in the responsibilities.
The clearance gate is nuanced: Basic Qualifications require an active Top Secret clearance with the ability to obtain TS/SCI w/ poly, but the Clearance Level field and Security Clearance Statement both state TS/SCI w/ Poly as the position requirement — classified here as TopSecretSci accordingly.
SOC classification is Low confidence: 'Systems Engineer' in the aerospace/defense space is a cross-disciplinary role (not purely software, IT, or hardware) that does not map cleanly to any single SOC code. 15-1299 (Computer Occupations, All Other) is used as the best available fit; 15-1211 (Computer Systems Analysts) is a plausible alternative given the systems analysis and integration focus.
Trade studies and program management support are listed as examples of Systems Engineering background in the Basic Qualifications section — these are captured under the Systems Engineering and Risk Management skills rather than emitted as separate generic methodology skills.
The salary range cited ($73,400–$129,260) applies specifically to Colorado (among other listed states); the posting notes the range may differ for other locations.
Ignored 4 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Systems Engineering, Risk Management, Engineering Change Management, Ground Command and Control Systems.
Requires a TS/SCI clearance — the cleared population is a small fraction of this occupation, so the real candidate pool is materially smaller than the estimate below, which does not model clearance.
